A small meeting September 29th in the Stairway to Heaven. Nikolaos Bezirgiannis and Sjoerd Visscher volunteered to help out Sean Leather with scheduling meetings each month. See About us.

For our August 25th meeting, we were joined by some students from Utrecht University's Summer School on Functional Programming. Jurriën Stutterheim talked about a project he did with Doaitse Swierstra and Wouter Swierstra. For the Junior College at Utrecht University, they developed a small web application to demonstrate the ideas behind Prolog and used this as a vehicle to teach about Computer Science in general. Next, Wouter Swierstra talked about his paper Data types à la carte, a way of solving the expression problem (with some caveats).

A group of Dutch HUG members visited Cambridge, UK in the weekend of August 12 for a Haskell Hackaton: CamHac.

Thursday July 14th Jasper Van der Jeugt talked about his Google Summer of Code project on switching the text library to use UTF-8 internally. Stefan Holdermans talked about how to do polymorphic Dynamics in Haskell as a library.

Wednesday June 15th, we met at Utrecht University for two talks by Stefan Holdermans of Vector Fabrics and Erik Hesselink of Silk. Stefan talked about his work with Juriaan Hage on a type and effect system for detecting wrong calls to `head` (and more complicated things). Erik discussed some common patterns found in database abstractions at Silk.

Wednesday April 13th, we met at Utrecht University where Thomas presented his talk on CodeDown, a universal approach to program documentation by embedding Markdown into the comments of any language. Per usual, we had some drinks afterwards at The Basket.

Tuesday, March 8th, a small group of Haskellers met in The Hague over diner and a few beers to discuss Haskell. Why is Cleans uniqueness typing so cool and what's up with DDC?

Monday, February 14th was a meeting with talks. Martijn van Steenbergen talked about Zwaluw, a library for bidirectional URL routing, and type-safe URLs. Marcelo Sousa just finished the Advanced Functional Programming course at UU and talked about his project work on parser memoization. Doaitse Swierstra discussed his continuing work on parser combinators. Afterwards, we relocated to The Basket for some drinks.

Thursday, January 13th, we met at the familiar Stairway to Heaven in Utrecht.

On Wednesday, December 8th, we met at the Stairway to Heaven in Utrecht over drinks. We talked about Haskell a lot.

In the weekend of November 5th a delegation of the Dutch HUG traveled to Ghent, Belgium to attend BelHac. On Tuesday, November 9th a small number of us met in the Stairway to Heaven over a couple of beers to discuss Haskell-related things.

On Thursday September, 9th, we met at the Utrecht University Library for three talks. Arie Middelkoop presented his talk "Breadth-first evaluation of non-cyclic, higher-order catamorphisms". Kevin Jardine talked about his web app engine in Haskell. Doaitse Swierstra described the latest developments in the UU parsing library.

In the midst of summer, August 14th, 2010, we met at the beach in Scheveningen. See Sean's photos from a sunny afternoon.

For the July 15th, 2010 meeting, we visited the Vector Fabrics offices in Eindhoven. After a tour around the office, we learned about vfAnalyst and discussed the differences between Caml and Haskell. Thanks to Wouter and Alexey for organizing this meeting.

The third meeting was on Wednesday, July 8th. We met over drinks in Utrecht and chatted about Haskell.

The second meeting was on Tuesday, June 9th at the top floor of the library in Amsterdam. We had interesting conversations, and more than one laptop was pulled out of its bag to show off some Haskell code!
